About this Temperature Converter
The Temperature Converter handles the three commonly requested temperature scales: Celsius, Fahrenheit and Kelvin. Unlike most unit conversions, temperature conversion requires both multiplication and an offset, so the tool applies the correct formula for each pair.

0°C converts to 32°F and 273.15 K. Likewise, 100°C converts to 212°F.
Frequently asked questions
Why is Kelvin different from Celsius?
Kelvin uses the same interval size as Celsius but starts at absolute zero, so 0°C equals 273.15 K.
Can Kelvin be negative?
Negative Kelvin values are not physically meaningful in ordinary thermodynamic temperature, although the converter performs arithmetic on entered values.
What is the Celsius to Fahrenheit formula?
F = C × 9/5 + 32.
